Bought a house 2 years ago and now that I have some time I wanted to upgrade the old Rain Bird system. The Rain Bird was mounted on a wall next to no outlet and is hardwired. I purchased a new Rachio 3, model 8ZULWCLITE, can i wire the Rachio 3 the exact same way as the Rain Bird?
@Spectre, the white in COM will go to any C in the Rachio 3 and the station wires in 1-5 slots go to the corresponding stations in the Rachio. The red and white wires on the left going to the 24vac will not be needed in the Rachio as it comes with a wall plug that powers the unit. Good luck.
@Spectre - Find out where the transformer to the RainBird is and replace that transformer with the Rachio transformer and splice in the brown carrier with the red and white wire into the Rachio wire so that the Rachio plug is used to power the unit. DO NOT connect RainBird 24 VAC wires (white and red) to the Rachio 24 VAC + and - terminals.
